RAILWAY SPLICE-BAR.

SPECIFICATION forming part of Letters Patent N 0. 395,924, dated January8, 1889.

Application filed May 31, 1888.

10 all whom it may concern: Be it known that I, GEORGE P. ROSE, a citiizen of the l nited States, residing at Fenton, county of Genesee, Stateof Michigan, have invented a new and useful Railway Splice-Bar, of whichthe following is a specification. This invention relates to the jointsand splice-bars of railways; and it has for its object a novelconstruction of the splice-bars, I whereby greater strength is securedand the bolts which secure the splice-bars to the rails are carried withthe rails in their contraction and expansion, the bolt-holes through therails being the size of the bolts instead of i elongated, as heretofore.

In the drawings forming a part of thisi specification, Figure l is aperspective view; Fig. 2, a cross-section, enlarged, on line 3 3 in Fig.1; Fig. 2' a cross-section on line 2 2 .1 in Fig. l, enlarged; Fig. a,an enlarged perspective of a part of the splice-bar; Fig. 5, aperspective of a portion of the splicebar; l ig. o, a perspective of alettered detail, hereinafter described; and Fig. 7 is aside elevation ofthe rails at the joint.

Referring to the lettered parts of the drawings, B are the rails withsquare ends at the joint. Each rail has a slot, '0, in the end, so thatwhen the rails are together end to end, as in Fig. 7, there is anelongated hole between, and partially in each rail, as at r in Fig. '7.The splice-plates are provided on the inside with a boss, c, Fig. 4., ofa size to fit the slot 1'. Fig. 3 shows these parts cfitting in the slotr from both sides. Thus by means of the boss on each splice-bar therails are greatly strengthened at the joint, and less strain comes onthe flanges of the splice-bars, and less dependence need be placed uponthe 5 bolts. The holes through the rails are the size of f the bolts.All the holes through the splicebars are as shown at a, Fig. 4f The bossof the washer A fits into the hole. a, but are I less in sizelongitudinally than the holes a, i and the bolt-hole through the washersis the size of the belt, for which reasons when the rails contract andexpand the washers slide in the holes a, because the bolts are carried lwith the rails and the washers with the bolts. The washers A on one sideare screwthreaded in their bolt-hole, and the threaded I ends of thebolts r, Fig. 2, are screwedl Serial No. 275,557. (No model.)

through them, and a lock-nut, u, is screwed onto said threaded end ofthebolt and against the washer A, Fig.

Having thus described the invention, what I claim as new, and desire tosecure, is-

1. The combination of the rails having the holes the size of the bolts,the washers provided with the boss, the splicebars having the slotslonger than the boss on the washer, and the securing-bolts,substantially as set forth.

2. The combination of the rails having the end slot and bolt-holes thesize of the bolts, the splice-bars having the central boss, and theslots to receive the washers, the washers having the boss of a lengthless than said washer-slots, and the securing-bolts, substantially asset forth.

3. The combination of the rails having the bolt-holes of a size to justreceive the bolts,

the splice-bars having the washer-slots, the washers having the boss ofa length less than said slots, the holes in the washers on one side ofthe rail being screw-threaded, and the bolts having the screw-threadedends in said screw-threaded holes, substantially as set forth.

4. The combination of the rails having the bolt-holes of a size toreceive the bolts, the splice-bars having the washerslots, the washersprovided with the boss of a length less than said slots, the holes inthe washers on one side of the rail beingscrew-threaded, the boltshaving the screwthreaded ends in said holes, and the lock-nuts on theextended ends of the bolts, substantially as set forth.

5. The combination of the rails having the end slots and bolt-holes, thesplice-bars provided with the central boss and having the iwasher-slots, the washers provided with the boss of a length less thanthe washer-slots, the washers on one side of the rail havin theirbolt-holes screw-threaded, the bolts having the screw-threaded ends insaid holes, and the look-nuts, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name inpresence of two wi tn esses.
